Tin is one of the many mining products found in the Bangka Belitung Islands region. Geophysical exploration was carried out in the Bukit Sambunggiri area, Merawang District, Bangka Regency using the dipole-dipole configuration polarization to detect polarizationel ectricity on surface of metal material and induction method to identify the distribution of tin deposit mineralization. The parameters is measuring area of 21 Ha with 6 tracks, length A, B, C is 640 meters, D, E, F is 840 meters, spacing between tracks 50 meters, spacing between electrodes 10 meters and equipment used is Multy Channel RS / IP Supersting. Processing measurement data using Res2dinv software to create 2D cross sections and Montaj Oasis for 3D cross sections. The results of resistivity and chargeability data processing of a total of six trajectories have 3 trajectories which have a clear mineralization area, that is, A trajectory is assumed to be at a distance of 250 - 350 meters and depths from 0 - 50 meters which are characterized by medium-high chargeability - 30) msec and low resistivity (<700) Ohm.m. On track D, it is estimated that there are three parts at a distance of 100 - 220 meters in depth of 50-50 meters, distance of 335 - 440 meters in depth of 50-130 meters and distance of 590 - 680 meters in depth of 50-130 meters. 430 meters at a depth of 0 - 150 meters. The results of interpretation of track A to track C are suspected to have zones of tin mineralization with secondary deposits and it is known that the mineralized zone is thought to be located below the bog iron zone with secondary tin deposits. This is due to the fact that the bog iron is hard rock like granite which is oxidized, so minerals that have a high level of resistance to weathering such as cassiterite and quartz will be released from the rock body and deposited in the lower layer. While path D to trajectory F is suspected to be the continuation of the zone of tin mineralization with primary deposits. This is presumably because the location of the mineralization area spreads between intrusion of granite rocks which have a high chargeability and resistivity value.

Underflow sluice box is a mineral processing tool that aims to separate the main minerals from associated minerals based on the principle of gravity concentration, which is equipped with boil boxes and underflow riffles as a separation medium in tin ore. The use of laboratory scale underflow sluice box provides Sn concentrate results with high Sn grade and recovery through the influence of underflow riffles and slope positions. Where underflow riffles parameters are in the position of 0.5 cm, 1 cm and 1.5 cm and the slope used is 0 °, 3 ° and 5 °, the experiment is carried out 9 times using 2 kg feed and the same Sn grade in each sample. From the results of the experiment obtained the dry weight and Sn grade concentrates which were analyzed by Sn grade using Grain Counting Analysis (GCA) and recovery calculations. After analysis and calculation, the highest Sn grade was found in sample 9 with underflow riffles position of 1.5 cm, slope of 5 ° and water flow velocity in the water flow velocity at 54 l/minute at 44.61 %, while recovery was highest in sample 3 with underflow riffles 1.5 cm, slope of 0 ° and water flow velocity in the water discharge at 54 l/minute at 99.13 %. Based on these results it can be said that if the underflow riffles and slope position is greater, the recovery and Sn grade concentrates are obtained high and if the underflow riffles and slope positions are smaller, the recovery is high with a low Sn grade concentrates.

CV Persada Tambang Intitama TK 4.218 Paku is a partner company of PT Timah Tbk, which conducts primary tin mining using the open pit method. Primary tin ore processing includes comminution, sizing, and concentration activities. Grinding using a Ball Mill is an advanced process that aims to reduce the grain size of the material in order to obtain finer grain sizes (fine material) and prepare the right grain size for the concentration process of 80 s.d - 200 mesh. In this study, the variables used are feed rate, number of Ball Mill revolutions (RPM), and water rate. The experiment was used 27 times by setting variables in combination to get effective scouring results. The material at the study site is divided into high grade and low grade materials with primary tin mineralization types in the form of stanniferous veins and gossan formed due to the oxidation process of polymetallic veins. Variable feed rate, number of Ball Mill revolutions (RPM), and water rate are very influential on the results of grinding. The higher the feed rate, the number of turns, and the rate of water the higher the Ball Mill scour, but if the variable is too high it causes overload capacity so that the output volume decreases. The effectiveness of the grinding results obtained in sample 24 with the highest production value reaching 93.9%. The effective value is obtained from setting the feed rate variable 5 to 6 Ton Per Hour (TPH), 80 rotation RPM, and water rate of 10.800 liters/hour (l/h). The result of the maximum feed rate that can be done is 9.86 TPH with LPT is 236.64 ton/day. Thus, the average LPT target of the company's 230-240 tons/day Ball Mill can be achieved
